Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a foldable running machine, and more particularly to a foldable running machine that is easy to store and that is safe and secure even when stored.

[0002]

[Prior art]

 5 to 7 show a conventional folding running machine. As shown in FIG. 5, a conventional foldable running machine is mounted on a base 1 having a frame structure that is placed on the floor upper surface in a substantially planar shape, and a top surface portion of which is substantially rectangular. The base 1 is provided with a traveling platform 2, and a lifting device 3 provided on the base 1. The base 1 is further provided with a rail 101. As shown in the figure, the elevating device 3 includes a threaded rod 302, a sleeve sleeve 301 with a female thread for screwing the threaded rod 302, and one end of the threaded rod 302. A motor 303 for driving the motor so as to extend and contract along the inside of the sleeve 301 with the female thread, and the other end of the motor 303 is guided by the rail 101 so as to be slidable back and forth. A first tie rod 304 pivotally supported at the distal end, one end of which is pivotally supported on the end of the first tie rod 304 and is guided by the rail 101 and slides, and the other end is provided with the internal thread. A second tie rod 305 connected to the end of the sleeve 301, and one end thereof is pivotally supported by the traveling platform 2 together with the other end of the first tie rod 304; 3 and a third tie rod 306 pivotally supported in the vicinity of the screw rod 302. The motor 303 drives the screw rod 302 to rotate and expand and contract along the female threaded sleeve 301. By moving the second tie rod 305, the first tie rod 304, and the third tie rod 306 in conjunction with each other, the tip of the traveling platform 2 can be raised and lowered to change the slope of the traveling platform 2. In addition, the first tie rod 304 and the third tie rod 306 are both pivoted by lifting the other end of the traveling base 2 about a point pivotally supported by the traveling base 2 as an axis. The traveling platform 2 is moved upright on the upper surface of the base 1 from the substantially horizontal use state in which the distal end is placed above the base 1, the front end is directed downward, and the other end is directed upward. The running machine can also be folded so that it can be moved to the stowed position. However, the folding running machine having such a configuration still has the following problems.

[0003] 1. In the use state (as shown in FIG. 5), when the other end of the traveling platform 2 is directly rotated to the storage state, the distal end of the traveling platform 2 abuts on the base 1. Therefore, as shown in FIGS. 6 and 7, before rotating to the storage state without fail, first, the elevating device 3 is operated to raise the distal end of the traveling platform 2 to a predetermined position at which the space between the traveling platform 2 and the base 1 is opened. There must be. That is, the conventional folding running machine requires two steps to achieve the purpose of folding, and has the disadvantage that the folding step is too complicated.

[0004] 2. In addition, as shown in FIG. 7, the traveling platform 2 stands upright in the housed state only by its own weight at the distal end portion pivotally supporting the first and third tie rods 304 and 306 (preferably, furthermore, a clock). Since it is held (close to the direction of rotation), if it is not stabilized and receives, for example, vibration or external force, it is easy to fall from the stored state to the used state, which is dangerous.

[0005]

[Problems to be solved by the invention]

 In view of the above, a first object of the present invention is to provide a folding running machine that can be easily stored.

A second object of the present invention is to provide a safe folding running machine that does not easily fall down even in a stored upright state.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a base having a substantially planar upper surface, an upper surface having a substantially rectangular shape, and one end in the longitudinal direction pivotally supported on the base. The base can be used in a state of use parallel to the base, and the other end can be lifted up and pivoted about the pivotal end to a storage state in which the base is substantially upright in a direction perpendicular to the base. In the folding running machine comprising a traveling platform, the base is provided with rail means along the longitudinal direction of the traveling platform in the above-mentioned use state, and the traveling platform is provided with substantially the pivot. Sliding means are provided near the support ends, and as means for pivotally supporting the traveling platform to the base, the traveling platform is substantially rod-shaped on both left and right sides, and both ends thereof are respectively the traveling platform and the base. Fixed means pivotally mounted on the holding means, whereby the fixing means The traveling platform can be rotated from the use state to the storage state by using the end portion pivotally supported by the traveling platform as an axis center and guiding the sliding means by the rail means. Provide a foldable running machine that is a special feature.

[0008] The folding running machine according to the above configuration is easy to store because the other end portion of the traveling platform in the use state can be directly turned into the storage state. That is, the present invention can provide a folding running machine that achieves the purpose of folding in one step. Further, in the folding running machine, in the storage state, the weight of the traveling platform itself is supported at the distal end by the holding means by pivoting one end to the base, and the other end by the other end. The traveling platform can be stretched and supported in the housed state. That is, this action is obtained at least equal to the horizontal distance between the pivotal ends of the holding means, and the present invention can provide a folding running machine that is stable and safe even after being stored.

In order to achieve an effect of securely fixing the traveling platform to the storage state, the base further includes the sliding means guided by the rail means and moved to the storage state. Stopping means for stopping the storage state may be provided.

[0010] Instead of the stopping means, it is substantially rod-shaped, and both ends thereof are the holding means and the other end of the traveling platform from the point where the securing means of the traveling platform is pivotally supported. When the traveling platform is pivoted from the used state to the retracted state while being pivotally supported at a position closer to it, the traveling platform may be pulled and extended by the rotating force to pull the traveling platform into the retracted state. Possible telescopic pokes, for example screw jacks, can also be provided. Further, needless to say, the stopping means and the telescopic poke rod may be provided at the same time. Thereby, since the traveling platform is securely fixed in the retracted state, even if the traveling table is suddenly shaken, for example, the traveling platform is immediately rotated from the retracted state to the use state, and there is a danger of damaging a person. I will not invite you.

The sliding means is substantially rod-shaped, and one end thereof is pivotally supported at a position closer to the other end of the traveling platform than a location of the traveling platform at which the fixing means is pivoted, The other end may be constituted by a support arm mounted on the rail means via leg wheels. Here, the support arm also has a function of fixing the traveling platform in the housed state.

[0012] The folding running machine of the present invention further has a substantially rod-like shape, which can be telescopically operated by a motor, one end of which is pivotally supported by the support arm, and the other end of which is provided. The traveling platform is pivotally supported at a location substantially closer to the side of the distal end portion of the traveling platform than the location where the holding means is pivoted, and thereby, in the use state, An elevating device capable of adjusting the slope of the traveling platform during use by raising and lowering the tip portion may be provided.

[0013]
